Hva betyr feilkoden?
The CEM has registered a low reading from the lock position sensor in the left rear door after unlocking. The fault is intermittent, so it may have occurred earlier without being active now. The cause may be a lock stuck in the locked position, an earth fault in the wiring or a fault in the lock motor circuit.
Mulige årsaker
- Lock stuck in the locked position
- Earth fault in the lock position sensor signal wire
- Relay fault or open circuit in the relay supply, such as a defective fuse
- Fault in the locking motor circuit
- Fault in the rear electronic module (REM)
Hva du kan gjøre
- 1Check that the lock has not stuck or jammed with the inside lock button, and that the lock unit is correctly fitted
- 2Check the connectors in the cable to the lock unit for loose connections and corrosion
- 3Check the fuse for the rear electronic module and replace it if it has blown
- 4Use a multimeter to check that the signal wire to the lock position sensor has no contact with ground (the body)
- 5If you have a diagnostic tool, lock and unlock the car and follow the lock position status of the left rear door in live data
